Early Embryonic Development Stages & Significance Video & Lesson Transcript
Important events that occur during the first week of human embryonic development include gamete approximation, contact and fusion of gametes, fertilization, mitotic cleavage of the blastomere, morula formation, blastocyst formation, and implantation of the blastocyst. Go to: Development

The point at which a zygote becomes an embryo occurs shortly after the fertilized egg divides into a ball of many cells, called a blastocyst, and implants itself into the uterus lining. In human.

The main difference between blastula and gastrula is in the structure and components of each of the embryonic stages. Blastula develops from the morula in a process called blastulation. It comprises of an inner cell mass, which develops into the embryoblast. The outer cell layer is the trophoblast, which gives rise to the placenta.

After the blastula develops, it undergoes transition to the gastrula (q.v.), a process called gastrulation. In organisms such as mammals, the earlier morula (q.v.), a berrylike cluster of cells, develops into a somewhat different form of blastula, the blastocyst (q.v.).

embryology mnemonic. Hey guys! so to remember the order of an embryo's development from a morula to blastocyst to gastrula I made up the mnemonic. (My = Morula, Baby = Blastocyst, Grows = Gastrula, Nicely = Neuralation) I hope this helps someone on test day! good luck! "More Blasting Gas, I'm Nervous" just adds neuralation after gastrulation!

The blastoderm becomes the morula, blastula, gastrula, and then neurula, as the development proceeds. A cell movement, termed the epiboly, begins in the early gastrula, and the blastoderm forms a sheet-like structure expanding over the yolk. Internalization of cells occurs in the pre-mid gastrula to form germinal layers.

DESARROLLO EMBRIONARIO
The gastrula stage is an important stage in embryonic development. During this stage, the blastula is reorganized into gastrula. Gastrulation meaning is that it takes place after the blastulation and gastrulation process, the embryonic layers or the germ layers are formed. These germ layers are further responsible for the formation of the organs.

Introduction Gastrulation is a critical process during week 3 of human development. Gastrulation is an early developmental process in which an embryo transforms from a one-dimensional layer of epithelial cells, a blastula, and reorganizes into a multilayered and multidimensional structure called the gastrula.

gastrula, early multicellular embryo, composed of two or more germinal layers of cells from which the various organs later derive. The gastrula develops from the hollow, single-layered ball of cells called a blastula which itself is the product of the repeated cell division, or cleavage, of a fertilized egg.

During gastrulation, the blastula folds upon itself to form the three layers of cells. Each of these layers is called a germ layer, which differentiate into different organ systems.

In line with the previous electrophysiological evidence demonstrating that embryos first become polarized at the blastula stage 16 , we found that Barium treatment affected embryonic development.

This division is taking place so quickly that the cells don't have time to grow, so the 32 cell stage known as the morula is the same size as the zygote. At this point, the zona pellucida (a protective membrane of glycoproteins that had surrounded the egg cell) is still intact, which also limits how big it can grow.

Morula and blastula are two early stages of an embryo in animals. After fertilization, a rapid cell division occurs in the zygote by mitosis. Small, spherical cells are formed from the zygote during this process, which is known as cleavage. These cells are called blastomeres.
